导致原因：升级到Java 11后，IntelliJ中的com.fasterxml.jackson.databind.ObjectMapper。java.lang.ClassNotFoundExcept

Posted 2021-04-10

升级到Java 11和Spring Boot 2.2.6 / Jackson 2.10.3之后，我无法在Intellij中启动我的应用程序。用maven编译后，用java -jar app.jar运行它就可以了。

虽然尝试在IntelliJ中运行，但出现以下错误：Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.databind.ObjectMapper

这里是完整的堆栈跟踪：

答案

1] java -jar app.jar这将打包您当前的代码，并需要将适当的文件添加到CLASSPATH。

2）现在，当您通过maven生成jar时，它将下载第3方必需的类，然后将您的应用程序打包到jar中，而jar中将包含前面提到的下载的类。因此，在运行该jar时，将显示所有必需的类。

我希望我清除了您对上述问题发生的原因的怀疑。如果没有，请联系我，我会尽力帮助您。

祝你好运，学习愉快！

另一答案

您不需要指定版本，因为SpringBoot会为您指定版本。
